What is electroluminescent LED device?

Electroluminescence (EL) is a process by which photons are generated when the excess electron-hole pairs are created by an electric current caused by an externally applied bias. It is known as the desired driving system in LEDs in terms of less energy loss that occurs from the operation of EL-LEDs than LCD due to the backlight.

Pb & Pb-free perovskite emissive layer (EML)

Halide perovskites have emerged as a promising optoelectronic material for light-emitting diodes. We are working on the synthesis of lead and lead-free perovskite Nanocrystals (NCs) for emissive layers.

Charge transport layer (CTL)

Our group research on charge transport layers (CTLs) including hole transport layers (HTLs) and electron transport layers (ETLs) in LED structure to improve the operational stability and efficiency.

Quantum dots (QDs) are a few nanometers semiconductor particles with unique optical and electronic properties by controlling its size via quantum confinement effects.
Our group focus on a wide range of quantum dots synthesis with in-depth analyses including II-VI, III-V and I-III-VI group QDs.

Phosphor-converted white light-emitting diodes (pc-WLEDs) are efficient light sources used in lighting, high-tech displays, and electronic devices. Our group defined zero thermal quenching which compensates the emission losses with increasing temperature.
